In view of the increasing demand for wireless information and data services, providing faster and reliable mobile access is becoming an important concern. Nowadays, not only mobile phones, but also laptops and PDAs are used by people in their professional and private lives. A mobile ad hoc network (MANET) is a spontaneous network that can be established with no fixed infrastructure. Ad hoc networks have a wide array of military and commercial applications. Security in mobile ad hoc networks is a hard to achieve due to dynamically changing and fully decentralized topology as well as the vulnerabilities and limitations of wireless data transmissions. Recent wireless research indicates that the wireless MANET presents a larger security problem than conventional wired and wireless networks. Distributed Denial of Service (DDoS) attacks has also become a problem for users of computer systems connected to the Internet. A DDoS attack is a distributed, large-scale attempt by malicious users to flood the victim network with an enormous number of packets. In this paper we describe the mechanism for detecting and preventing DDoS in ad hoc network.
